y Be it known that I, HAERYC. FERGusoN, a citizen of theUnited States, residing at Canton, inthe county of -Starkand 'State' of lto Ohio, haveinvented certainqnew and'useful l Im rovements inVac'uum Preserving-Recep- Vtac es; and Idoherebydeclare that the following isa full, clear, and exact 'description of thes'ame;` reference being: had tothe annexed drawings,l making a part of this specication, and to'thegur'es of reference marked y thereon, in Which- Figure 1 is a longitudinall vertical section.I

Similar numerals of reference indicate cor responding parts in all the iiguresof? the draW- i ings. f, In the" accompanying drawings, 1 re resents the bod preferably cyhndricalfin cross` section. and

. which bottom is convexeconcave and the maybeformed of any desired size,`reierence being had to the capacity .of`` the receptacle designed to be'constru'cted. To the' lower` 4end ofthe body 1 is. attached ..the bottom 2,

securely attaching the bottom to the body 1 l a by means of thel rivets 4" or their equivalents.

For the ur ose hereinafter describedv the flange 3 s ou d be y"so, formed'and the inner' surface of the body also that when the flange 3 is brought up against the inner surface, ofv

the body v'1 la close fit will be produced.

To thetop or upper endof the body 1 is securely attachedthe curved cover portion5,

which is 4providedwith the flange 6', which flange is connected to the top yor upper end of the body 1 in' substantiallythe samemanner as theflange' of the bottom 2. To the coven portion issecurely'attached the ringr7, the

. under side of which is curved to correspond with the curvature of theupper face 4of.' thev The ring.7 is provided with the annular flange. 8 which annular flange abutsagainstthe inner edge of the cover-section 5, as illustrated .inFigs 1 and 2. For' cover portion 5.

employed'.l c The ring 7 is provided with an des1red number-of notched lugs 10, whic 'notched lugs are' for .the purpose hereinafter described.- Upon the top-orupper side of thering 7 is located theY asket 11 and theremovable-couver 12 ,place u on the gasket 1-1, as" illustrated F1 1.

lugs A13, corresponding with-"thenotched lugs l10, formed upon thel ring 7. In thenotched lugsare located the clamping-bolts`14,which clamping-bolts arefor the purpose' of securely seating' the cover -1'2 f and fc 11 between the upper edge of'the ring 7 and amping the gasket T e cover 1 2 is conveXo-concave and 1sr provided with notched A7o the lower contact l edge oi the cover 12. For the purpose hereinafter described the joints of the body 1 are covered by contact-strips 11, which contact-strips overlip the joint 16 of the'body 1, as 'illustrated in ig. 3.

Within hebody .1 is located thebrous 1in'- ing 17, which may-be of any suitable material,l and if in the event eggs are to bepreserved suitable eglgvcasings or receptacles, suchas 1 8, toget within the body 1 and the removab e parts of vin the rece .tacle is with'- um, orl substantially so, and lfor the purpose of determining the quantity of'air'rernoveda will be understoo'd that the atmospheric pressurel islof a considerable force, and when rosityof thel m'ateriah'land'fin` order to overcome th1s objection-amb at the samev time producing a (receptacle that will' be light or may be constructed of light material the boter with the eggs placedf Vthe "1eceptacle brought into roper position. j and connected so ,as to pro uce as' near as" lpossibleanair i 'htv receptacle, aterwhi'ch 'the lair centaine `drawn through thevfpipe4 19 y means of a.

tom 2, the cover-section" 5, and the`cover'12 are formed so as to present convexed outer.

.surfaces It will be" understood that by so'k forming the parts any atmospheric pressure will have a tendency to close the outer pores of the metal, thereby decreasing the the top and bottom of. the receptacle straight or in planes the tendency is to bend or spring the bottoms inward during the time the air is withdrawn from the receptacle and again? when* the air is admitted to allow or permit the tops and bottoms to assume their normal positions, by which action the porosity of the metal is continually increased and the joints have to become loose and adinitfthe seeping in of the air; but by my peculiar arrangement this difficulty is overcome, and for the purpose of providing for the downward pressure of the cover-section so that there may be no relative movement as between said cover-section and the ring 7 said ring .is provided with the annular flange 8, which annui lar `lange abuts against the inner edge of the cover-section 5.

It will be understood that the pressure upon the body 1 will' be the saine upon the top and bottom of the receptacle, and by providin the top and bottom with outer convexef surfaces the pressure upon the body 1 and upon the tops andv bottoms will be equalized in su'ch a manner that there will be no relative movement as between said parts regardless of the-outer atmospheric pressure varying from time to time as against the inward pressure or non-pressure.

The object and purpose of providing the means for conveniently removing the cover 12 by simply loosening the nuts upon the clam ing-bolts 114 and removing a portion of the camping-bolts.

In Figs. 5 and-6 I have illustrated a modiied form for connecting the cover 12, which l l i l l i i i l i I r i l i i i i r i consists in a spider yoke 21, coi'inected to the ring 7, and the ring 7, provided with the s )i- .f der yoke-engaging lange 22 and the spi er porosity of the material, Whereas by forming yoke provided with the clamping-screw 23, which screw can be rotated by the wheel 2-1, so as to clamp or press the cover 12 in close contact upon the gasket 11.

Having fully describedniy invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a vacuum preserving-receptacle, the

, combination of-a body having secured thereto a conveXo-concave bottom, a cover-section formed conveXo-concave and provided with an attaching-flange, a rinlr secured to said cover-section and provided` with an annular {iange adapted to abut against the cover-section, a removable cover formed convexe-concave, and means for attaching said cover to the ring fixed to the cover-section, and a gasket located between the removable cover and the ring, substantially as and for the purpose specified.

2. In 'a vacuum preserving-receptacle, a body provided with a conveXo-concave bottom, a cover section or ring formed convexeconcave and provided with an attachin iange, a rinfr connected to the cover-section andprovide with an annular flange adapted to engage the cover section, a removable cover Iorn'ied convexo-concave, and a gasket located between the cover and the ring, and means for securing the removable cover, subl stantially as and for the purpose specified. notched flanges 10 and 13 is to providea l In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
